AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
900 AM PDT SUN MAR 18 2012

.SHORT TERM...A SHORTWAVE TROUGH IS SHIFTING EAST OVER THE AREA
TODAY. THIS IS BRINGING LIGHT SHOWERS TO THE AREA THIS MORNING.
SHOWERS WILL CONTINUE THROUGH THE AFTERNOON. VERY COLD AIR ALOFT
AROUND -33 TO -35 DEGREE C WILL BRING WEAK INSTABILITY TO EASTERN
PORTIONS OF THE AREA. SHOWERS COMBINED WITH WEAK INSTABILITY MAY
ALLOW SOME ISOLATED THUNDERSTORMS TO DEVELOP OVER PORTIONS OF THE
AREA EAST OF THE CASCADES. SO HAVE ADDED A SLIGHT CHANCE FOR
THUNDERSTORMS INTO THE FORECAST. ELSEWHERE EXPECTED A COLD SHOWERY
PATTERN. SOME MODERATE SHOWERS MAY HAVE GRAUPEL OR SMALL HAIL IN
THEM. SNOW LEVELS ARE DOWN TO 500 FEET THIS MORNING AND WILL
GRADUALLY RISE TO AROUND 1500 TO 2500 FEET THIS AFTERNOON.

MODELS SHOW SHOWERS DECREASING IN THE EVENING. THEN A WEAKENING
FRONT MOVES INTO THE COAST WHILE A RIDGE BUILDS OFFSHORE. THIS
FRONT WILL BRING ONLY LIGHT PRECIPITATION...WITH BEST CHANCES FOR
LIGHT RAIN AND SNOW ALONG THE COAST AND JUST INLAND THIS EVENING
INTO TONIGHT. OTHERWISE...THE MAIN CONCERN WILL BE HOW COLD
MONDAY MORNING TEMPERATURES WILL GET. THE CURRENT FORECAST CALLS
FOR LOW 30S NEAR THE COAST AND MID 20S TO LOW 30S INLAND ON THE
WEST SIDE TEMPERATURES IN THE TEENS EAST OF THE CASCADES. THE
POTENTIAL FOR FREEZING CONDITIONS ON THE COAST MAY DEPEND ON THE
AMOUNT OF CLOUD COVER AS THE WEAK FRONTAL BOUNDARY MOVES TOWARDS
THE AREA TONIGHT. CURRENT GUIDANCE SUGGESTS THAT FREEZING
CONDITIONS MAY BE LIMITED TO THE CURRY COAST AND SOME INLAND AREAS
OF COOS COUNTY.

MONDAY...A LOW TO THE NORTHWEST WILL BRING A WARM FRONT TOWARDS
THE COAST...THEN INLAND MONDAY NIGHT. SNOW LEVELS ARE EXPECTED TO
INCREASE TO 2500 TO 4000 FEET AHEAD OF THIS FRONT THEN TO 4000 TO
6000 FEET ON TUESDAY. AREAS OF MODERATE PRECIPITATION ARE EXPECTED
MONDAY NIGHT INTO TUESDAY WITH THIS SYSTEM ESPECIALLY FROM THE
CASCADES WEST. THIS FRONT MAY ALSO BRING STRONG GUSTY WINDS TO THE
COASTAL WATERS AND COAST. INLAND AREAS WILL ALSO SEE GUSTY SOUTH
TO SOUTHWEST WINDS. OVER THE SUMMER LAKE AREA...SOUTHWEST WINDS
MAY INCREASE WITH GUSTS TO 40 TO 50 MPH MONDAY NIGHT AND TUESDAY.

WET CONDITIONS CONTINUE THROUGH WEDNESDAY AS ANOTHER STRONG FRONT
MOVES INTO THE AREA. SNOW LEVELS WILL REMAIN ABOVE 4000
FEET...LOWERING WEDNESDAY NIGHT BEHIND THE FRONT.

&&

.AVIATION...MOUNTAINS WILL BE OBSCURED ACROSS THE FORECAST AREA
TODAY...AND CONDITIONS WILL GENERALLY BE MVFR WEST OF THE CASCADES
WITH MOSTLY VFR CONDITIONS EAST OF THE CASCADES. OCCASIONAL RAIN AND
SNOW SHOWERS WILL DROP VISIBILITY LATER THIS MORNING FROM THE
CASCADES WESTWARD...AND THIS SHOWER ACTIVITY SHOULD LAST THROUGH
EARLY AFTERNOON.

&&

.PREV DISCUSSION... /ISSUED 315 AM PDT SUN MAR 18 2012/

DISCUSSION...TWO MAIN FEATURES WILL AFFECT OUR WEATHER THROUGH
THE MIDDLE OF NEXT WEEK. FIRST...A WEAK SHORTWAVE TROUGH WILL
SWING THROUGH THE FORECAST AREA TODAY...FURTHER COOLING THE AIR
MASS AND PRODUCING SNOW SHOWERS OVER MUCH OF SOUTHERN OREGON AND
NORTHERN CALIFORNIA. NEXT...A POTENT FRONTAL SYSTEM WILL BRING A
PERIOD OF WET WEATHER TO THE AREA FROM MONDAY NIGHT THROUGH
WEDNESDAY.

TODAY...AN ILL-DEFINED TROUGH FEATURE THAT IS FOLLOWING THE DEEP LOW
OVER THE GREAT BASIN IS REACHING THE OREGON COASTLINE. SOME
DEFORMATION BEHIND THE DOWNSTREAM LOW SEEMS TO BE EVIDENT ON
SATELLITE IMAGERY...AND THIS COULD ENHANCE PRECIPITATION TODAY.
RADAR RETURNS ARE NOT VERY IMPRESSIVE RIGHT NOW BUT SNOW DOES SEEM
TO BE EXPANDING SOME...SO HAVE KEPT WINTER WEATHER ADVISORIES FOR
AREAS WEST OF THE CASCADES...GENERALLY ABOVE 1500-2000 FEET.
NAM...GFS...AND THE HIGHER RESOLUTION HRRR HAVE CONSISTENTLY
INDICATED SHOWERS INCREASING IN COVERAGE TODAY...SO EXPECT 1 TO 3
INCHES IN THE HIGHER ELEVATIONS TODAY. SEE THE WINTER WEATHER
PRODUCTS AT PDXWSWMFR FOR MORE DETAILS. SNOW IMPACTS WILL BE MUTED
IN THE LATE MORNING HOURS AS TEMPERATURES WARM SOME...MAKING IT
MORE DIFFICULT FOR ANY LINGERING SNOW SHOWERS TO STICK TO ROADS.
SHOWER ACTIVITY SHOULD BE MOSTLY OVER BY TONIGHT.
ADDITIONALLY...THE COQUILLE RIVER AT COQUILLE CONTINUES TO
FLOOD...AND SHOULD GRADUALLY LOWER THROUGH TODAY.

BELOW NORMAL TEMPERATURES ARE EXPECTED TODAY AND MONDAY
MORNING...WHICH WILL LIKELY BE THE COLDEST MORNING FOR THE NEXT WEEK
OR SO. GIVEN THE EXPECTED MEDIUM TO HIGH AMOUNT OF
CLOUDS...TEMPERATURES ARE FORECAST TO STAY IN THE UPPER 20S FOR WEST
SIDE VALLEYS. HOWEVER..THERE IS SOME UNCERTAINTY REGARDING HOW
MUCH BREAK IN CLOUDS THERE COULD BE AHEAD OF THE NEXT WEATHER
SYSTEM ARRIVING MONDAY. ALSO...DEWPOINTS SHOULD BE IN THE MID 20S
THIS AFTERNOON INTO EVENING. THEREFORE...A FREEZE WATCH HAS BEEN
ISSUED FOR PARTS OF JOSEPHINE...DOUGLAS...AND JACKSON COUNTIES.
ADDITIONALLY...A FROST ADVISORY HAS BEEN ISSUED AGAIN FOR THE
COASTAL AREAS. SEE PDXNPWMFR FOR MORE DETAILS ABOUT THE POTENTIAL
FOR FREEZE CONDITIONS.

THE NEXT SYSTEM TO AFFECT THE AREA WILL BE ATTACHED TO A PARENT LOW
THAT DEEPENS OVER THE GULF OF ALASKA ON MONDAY. THIS WILL SET UP A
FETCH OF HIGH PRECIPITABLE WATER VALUES THAT WILL OVERRUN A WARM
FRONT MONDAY NIGHT...AND GENERATE A PERIOD OF MODERATE TO HEAVY
PRECIPITATION...ESPECIALLY OVER THE COAST RANGE. FROM MONDAY NIGHT
THROUGH WEDNESDAY ABOUT 5 INCHES OF RAIN IS POSSIBLE TOWARD THE
CURRY COUNTY COAST WITH 3 INCHES NEAR THE COOS COUNTY COAST...AND 2
TO 3 INCHES OVER THE CASCADES. SNOW LEVELS WILL BE ABOVE 5000
FEET...ESPECIALLY PRIOR TO WEDNESDAY...AND THIS WILL CAUSE
RIVERS...CREEKS...AND STREAMS TO RISE AGAIN.

LATE NEXT WEEK MODELS SUGGEST SEVERAL POSSIBILITIES...ONE OF WHICH
INCLUDES A CUTOFF LOW MEANDERING SOUTH ALONG THE COAST. IN ANY
CASE...CONFIDENCE IN THE EXTENDED IS LOW AND MINIMAL CHANGES WERE
MADE TO THIS PORTION OF THE FORECAST.
